You could try mgetty. Mgetty is a ‘‘smart’’ getty replacement, designed to be used with hayes compatible data and data/fax modems. Mgetty knows about modem initial- ization, manual modem answering (so your modem doesn’t answer if the machine isn’t ready), UUCP locking (so you can use the same device for dial-in ...

The HylaFAX Handbook has some documentation about making sure you have a compatible fax device. According to that document, external serial modems will work almost without exception, but some external USB modems may be softmodems and require a driver. Regarding internal modems, that document references some chipsets and model numbers that are known to work. ...

From what you say (serial interface, AT command set), I think it would behave like a dial-up modem. Thus you could use something like wvdial or ppp to connect using it. Also, this repo on GitHub looks relevant: This repository serves to group together a bunch of scripts I've been writing to assist in the development process with the Telit 862GPS. They ...

The easiest way to use linux to answer the phone is with the Asterisk program. You should be able to yum install asterisk on your linux machine. You then connect an analog adapter to your network and connect your phone line through it. This will allow you to answer the call, see the caller id if the caller id information is sent from your LEC, record the ...

External modems that plug into a serial (RS232) or USB port usually have all the necessary electronics. Most Winmodems (requiring Windows software to supplement their deficiencies) are internal. “Hayes compatible” or a mention of compatibility with DOS, OS/2, Linux, SCO, or anything other than Windows is an indication that the modem will just work under any ...

If you want to turn a serial port into a network interface, that is exactly what PPP (pppd) was designed to do. It'll work over anything that looks like a serial port to Linux. pppd supports sending out "chat text" which contains the necessary AT commands to setup and teardown the call. You'll probably want to make your own chat script for this device. ...

I wouldn't recommend using a typical data/voice modem for this. Even 15 years ago, when modems were current technology and there was lots of competition for features and technology, they were a pretty low-grade way to do the sorts of things you're asking for. Now, after a decade of race-to-the-bottom activity exemplified by the near universal takeover of ...

I'm with @Renan: it looks like this problem was fixed in newer kernels. (One such thread on LKML.) The key error is the invalid interface number one. It means the USB driver sees the device, but it's numbering its features (interfaces) in a way the driver doesn't expect, and it can't cope. Googling around, you can find several cases where people are fixing ...

Doing a search on Google for this, I (hopefully) found the answer to your question on: Ubuntu Forums. It shows the exact steps to download the E353.tar.gz file and shows the instructions on how to install it. Hope it helps.

If you loosen the requirement for using ttyUSB0 - ttyUSB31, then you may just have a possibility. What I've done is let udev create symlinks to the device nodes assigned by the kernel. You cannot reliably hardwire a physical device to use ttyUSB0, you can however reliably add a symlink ttyUSB001 to point to whichever device node you want. The trick here is ...

You could play a little with cts, rts or other serial status lines and check if the modem responds to lowering/raising that signal correspondingly. But your modem may be configured to ignore these lines, or there might be other devices that also react to those changes. I think psusi got the correct answer. I remember I once debugged hylafax to get the idea ...

You could try taking a look at mgetty, though I never tried anything of the sorts. Smart Modem getty replacement Mgetty is a versatile program to handle all aspects of a modem under Unix. This package includes basic modem data capabilities. Install mgetty-fax to get the additional functionality for fax. Install mgetty-voice to get the functionality ...

you can only see the signal strength by adding this line into wvdial.conf : Init4 = AT+CSQ The Values are Min-Max = 0 - 30. For the type of connection you can only see it by the lights on the device. EDIT: AT^SYSINFO gives different useful information, among these is the connection type.

chat & pppd chat is a program that the pppd program can use to dial a modem connection. It is provided with a script of that describes the conversation required to establish the connection. (A conversation in this context is a series of commands issued by chat, and responses received from the modem.) pon & poff pon and poff are commands used to ...

Check /etc/ppp/options. DO NOT Edit this file, rather copy it to some location and make edit. check this: # Disable Address/Control compression negotiation (use default, i.e. # address/control field disabled). #-ac More info you can find here in the PPP-HOWTO.

I believe you can use Wireshark to determine why these packets are being retransmitted.

Important: you can always override your default options with local options. from man pppd /etc/ppp/options System default options for pppd, read before user default options or command-line options. and also ~/.ppprc /etc/ppp/options.ttyname /etc/ppp/peers you should enable debug options (sometimes also kdebug) debug ...

Solution 1: Run dmesg and watch out for ttyUSB* lines if your modem interface is a classical emulated serial interface. Solution 2: Browse /sys/bus/usb/devices/X-1:Y:*/ until you find useful information. Based on your line Bus 003 Device 013: ID 0421:0007 Nokia Mobile Phones, i would guess X=3 and Y= 12 (13 minus one). Solution 3: Run udevadm monitor as ...

I believe you can use the command ppstats -z to display compression statistics. If it displays all zeros then compression is not enabled. excerpt from man page -z Instead of the standard display, show statistics indicating the performance of the packet compression algorithm in use. When the -z option is specified, instead displays the ...

Wait—I see it. Two things: You used ATTRS{product}=="6011" when you meant ATTRS{idProduct}=="6011" That missing id will break it. Copy-and-paste from udevadm info --attribute-walk to prevent typos like this. Your pattern is wrong; it should be KERNEL=="ttyUSB[0-9]*". Its a (very limited) regular expression, so [0-15]* means "any of the characters 0–1 or 5, ...

[EDIT] I found a post with instructions - I'm not sure how current that is. It looks like you use Puppy's own Internet Connection Wizard (launched by an icon labeled "connect"), which has an option "Internet by dialup analog or wireless modem". That shows PupDial, which can be used to establish a connection using your modem. Below is a description about how ...

Most 3G modems are supported in Linux, I've used several different models, (mostly Huawei) on embedded devices using standard linux packages and libraries - they all do pretty much the same thing, just with brighter lights or faster stripes Good starting points are wvdial and pppd. The main obstacle to overcome is working out the individual methods each ...

Some systems will drop idle dial-up connections. This could be happening on either end of the connections. IPSs don't like people tying up their dialup pool with idle connections. Maximum dial-up speed is 56k on a clean line. It is common for the modems to downgrade the connection speed on a noisy line. If the line is noisy enough the connection may ...

As much as this question is very old and answered. I would like to add something further. For USB modems, "cdc-acm" compliant USB modems will present themselves as a serial device. They are usually self contained and small, with all required hardware. Latest verisions of linux kernel has a module to support these kind of devices out of the box. Some ...
